Improvement in loom-shuttle guards



UNITED STATES PATENT OEEIoE.

MATTHEW PICKLES AND THOMAS PICKUP, OF LAWRENCE, MASS.

IMPROVEMENT IN LOOM-SHUTTLE GUARDS.

Specification forming part of Letters Patent No. 156,943, dated November 17, 1874; application filed July 20, 1874.

To all whom it may concern:

Be it known that we, MATTHEW PIoKLEs and THOMAS PICKUP, both of Lawrence, in the county of' Essex and Commonwealth of Massachusetts, have invented a Safety-Guard for Shuttles, of which the following is a specication:

The object of our invention is to furnish a guard for shuttles, which shall be simple and durable in its construction, and effective to prevent the shuttle from leaving its accustomed course, as is often the case, not only to the injury of the fabric being woven, but often to the injury of the operative. Our invention consists in the arrangement of devices, hereinafter described, for attaching the guard to the lathe, and connecting it to the crankrod so that thedesired operation is attained viz., the guard is in proper position to prevent the shuttle breaking its couse when passing through the warp, forming a box by be ing brought down to the warp, and being raised when the filling is being beat up by the reed.

In the drawings, Figure 1 is a front elevation of a loom with our improved guard attached, of which AA is the frame, B B, the lever-arm; C O, the lathe D, the reed-cap; E, our improved guard a a, the picker-sticks; H H, the picker-straps; J, the strap-spring. Fig. 2 is an end elevation; E, the guard; K, the lever-arm; L, the rod connecting the lever-arm K with the crank-rod M N, the crank, and O the crank-shaft. Fig. 3 is a top elevation, showing ourimproved guard as attached to the loom.

Similar letters indicate the same parts in each of the drawings.

In the arrangement and construction of our improved guard We first form, of wood or iron, a guard of sufficient length to extend over the shuttle course, and then attach to each end of it lever-arms, which we pivot at or near the center to the reed-cap stands of a loom. The ends opposite to those attached to the guard are pivoted to the crank arms or rods.

In the operation of a loom with our improvement attached, the guard E is reciprocated by the oscillation of the crank-rod M, the guard being brought near the warp, and forming a box so that the shuttle is held in its direct course when it is passing through the warp, and elevated when beating up the filling or woof.

We are aware that it is not new to apply shuttle-guards to looms, and to so construct them as to be operated by the crank-rod of the lay, and we make no claim thereto. Therefore,

What we claim as our invention, and dcsire to secure by Letters Patent, is

The guard E, the lever-arms K K, the connecting-rods L L, and the crank rod M, all arranged and operating together as and for the purpose set forth.
